A full backup should be performed before any patch is applied. There is no automated roll-back.

Zimlet patches can include removing existing Zimlets and redeploying the patched Zimlet.

Only files or Zimlets associated with installed packages will be installed from the patch.

Switch to user zimbra before using ZCS CLI commands.

Important! You cannot revert to the previous ZCS release after you upgrade to the patch.
